Your identification has been saved in /home/user1/.ssh/id_rsa.
Your public key has been saved in /home/user1/.ssh/id_rsa.pub.
The key fingerprint is:
blah:1b:42:ba:blah:ec:41:blah:01:blah:73:83:99998: 8a:fb:99 user1@fileserver

So now you have created your rsa keys.
Now what you need to do is create a autorized_keys file on Server2, do this
by doing the following, (make sure you are in the "/" directory before
running)

sftp ip_server2 prompt password

cd /home/user1/.ssh (in server2)
put /home/user1./ssh/id_rsa.pub

in server2

cat /home/user1/.ssh/id_rsa.pug >> aythorized_keys

After you should able to ssh or sftp to Server2 from Server1 without being
asked for a password
